20080246396 | Electroluminescent Element - An EL element includes a light-emitting layer ( | 10-09-2008 |
20080283380 | PRESSURE SENSITIVE CONDUCTIVE SHEET AND PANEL SWITCH USING SAME - A first resistor layer is formed on the lower surface of a base in film form, and at the same time, a second resistor layer in which particles of different particle diameters are dispersed is formed and layered on the lower surface of the first resistor layer, and thus, a pressure sensitive conductive sheet is formed. In this configuration, the second resistor layer in uneven form makes contact with the fixed contacts in accordance with a pressing force so that electrical connection is made via the second resistor layer and the first resistor layer, and therefore, a thin panel switch with little fluctuation in the resistance value resulting from repeated operation where a stable resistance value can be gained can be realized. | 11-20-2008 |
20090173608 | LIGHT-GUIDE SHEET, MOVABLE CONTACT UNIT AND SWITCH USING THE SAME - A light-guide sheet includes a light transmissive film substrate, and luminescent protrusions formed at predetermined points on the substrate. At least one of the substrate and each of the luminescent protrusions is colored to a color tone that absorbs yellow light more than blue light. Alternatively, a reflective layer colored to a color tone that absorbs yellow light more than blue light is provided on at least one of the top and bottom faces of the substrate. | 07-09-2009 |
20100140069 | Light Guiding Sheet and Movable Contact Body Using the Same - A concavo-convex light emitting section provided on an under surface of a base material is formed of a synthetic resin with inorganic oxide dispersed therein. A larger amount of light is reflected by inorganic oxide having a large refractive index and dispersed inside the synthetic resin, to cause a plurality of light emitting sections to emit bright light with a small number of light emitting elements. A light guiding sheet capable of making bright and uniform illumination and a movable contact body using the same are realized with a simple configuration. | 06-10-2010 |
20100207907 | TOUCH PANEL AND METHOD OF DETECTING PRESS OPERATION POSITION THEREON - In a touch panel, one of conductive layers on a bottom of an upper substrate and on a top of a lower substrate is formed of belt-shaped conductive layers. The other is a single conductive layer facing the belt-shaped conductive layers. The single conductive layer is provided with a pair of electrodes in positions corresponding to both ends in a direction where the belt-shaped conductive layers extend. When the upper substrate is pressed while a voltage is applied between the pair of electrodes, the top and lower conductive layers contact with each other. Then, a voltage value corresponding to the pressed position in the direction where the belt-shaped conductive layers extend is generated from any of the belt-shaped conductive layers. From the voltage value and the position of the belt-shaped conductive layer from which the voltage value is generated, a pressed position on the upper substrate can be detected. | 08-19-2010 |
20110198204 | LIGHT GUIDE SHEET, AND MOVABLE CONTACT UNIT AND SWITCH USING LIGHT GUIDE SHEET - A light guide sheet has a light-transmissive film-shaped base material, and a convex first light emitting section formed on the base material. In the first light emitting section, a fluorescent pigment and a dyeing pigment are dispersed. The light guide sheet of the present invention emits light of a pure and vivid color by using the fluorescent pigment and the dyeing pigment. | 08-18-2011 |
20110280024 | LIGHT GUIDE SHEET AND MOVABLE CONTACT UNIT INCLUDING THE SAME - The light guide sheet has a base of a light transmissive film, a first light-extracting section, and a second light-extracting section. The light-extracting sections having pits and projections are formed on a surface of the base. The base has a first color converter at least at a part corresponding to the position having the first light-extracting section in a thickness direction of the base. The first color converter converts light from a light source into a first color. Forming a color converter for predetermined color at each part corresponding to a plurality of the light-extracting sections allows the one color emitted from a light-emitting element to be converted into differently colored light beams at the light-extracting sections. The structure offers various patterns of illumination without increase in number of the light-emitting element. | 11-17-2011 |
20110315534 | LIGHT GUIDE SHEET, MOVABLE CONTACT BODY USING SAME, AND SWITCH - A light guide sheet guides light emitted from a light introducer. The light guide sheet includes a film-shaped substrate, a light emitting section formed on the substrate, and a belt-shaped light-blocking section. The light emitting section reflects or scatters light transmitting in the substrate to the outside. The light-blocking section is formed in the substrate by coloring a position of the substrate to a color. In the position, the light emitting section is not formed. The color absorbs the light which is emitted from the light introducer. The light emitting section can alternatively be composed of a plurality of projections and/or a plurality of recesses. Such a light-blocking section is formed in a position of the substrate where the projections and/or the recesses are not formed. | 12-29-2011 |
